TALKING Macri-INE.

'Appiiation inea May 5, 19,20'. serial Na'eaosz; i

My invention lrelates to talking machines and more particularly to such a.type of machine vasfma'y be conveniently moved from ,place 'to.place,' and known commercially as the portable7 type; t d

The objects of 'the invention are to produce a portable talking machine Which Will be compact, in `which a plurality of'records may be protected rand transported', in which .the mechanism may be protected from injury during transportation, which will be VAneatand attractive in lappearance, andvhich Will provide means for retaining record discs in position lsecured from'possible break- 'age While, not in use.v

AWith these and other objects'in view to be more fully set forth hereinafter, the invention consists' in the novel construction,

combination of elements, and arrangement of partswvliich Willl be exemplified in the operation and construction hereinafter described in the specification and illustrated in the accompanying drawings, considered Vtogether or separately,v .f

The inventive idea involved 'is capableof receiving la variety ofmechanical eXpres-.

v sions, one of Which for the purpose of illus- .trating the invention is vshown in the accompanying-drawings. fi i The invention Will be first described in connection lwithl ythe `accompanying drawings, illustrating one embodiment'ofthe 'invention, 'wherein similar reference characters are used tov designate corresponding .parts throughout the several views, and then more specifically defined and indicated in the appended claim. In the drawingsff Fig. 1 is a top plan View of a portable talking machine embodying the invention, the lid or cover being in open position; 'Figz 2 is a detail section on the line 2 2 of Figl, with the cover in closed position Fig. 3 is a detail section on theline 3,-3

' v,receive a nut 22.y

ofFig. l; and v l s l x Fig. 4f is a.r detail sectional vien7 of the record disc support.

In carrying out the invention, I employ a phonograph or talking machine of the disc record type and of any desired construction. The talking machine comprises a motor 1, a turn-table spindle 2, a turn-table 3, a tonearm 4, carrying the usual sound-box or reproducer 5, which, when in operative position, is vin communication with a horn 6,

lThe horr'iis below the 'usual' motorl board 7,y andy has a contracted y'neck and a flaring `open front end 8. The 'motorfboard is mounted Within -a casing 9Uprefer`ably^0f rectangular. form, and the bottom =10 ofthe casing andthemotor board 7 may form the t' bottom vand top of the horn if desired. t

'The frontend llof the -casing 9gi's prefcrably* hinged along the edge `of the bottom of the casing lwhereby said side may be lowered to disclose the open flaring end of the horn. The end 11 may be providedwith a handle by means of Whichthe casing may be carried.

`The spindle2 projects throughy the motor that` it Will rotate With the spindle.'

The tone-arm 4l is adapted 'to communicate With the horn through a collar 12 carried on the motor board,fand tlietone-arm is 'readily removable from the collar'.

The4 motorboard is: cut'a'vvay at 13 and i partitions 14,'15 andl are positioned' bet y l ltWeerrthe motor board and the' bottom 10 of the casing. The compartment thus formed arm with' the sound-box attached.` The tone-arm and'sound-box Will snugly fit Within thel compartment and vwill be 'prevented from, rattling therein, and `said' compartis of a sizeand shape to receive the tonefrom injury. vThe coverfl is provided with i a lip 18 `vvhereby the same may be raised.

The upper, exposed end of the turn-table`v spindle 2 instead-'of being spherical as lis.l common, is flat, and is provided with an axial, screw threaded recess 19 adapted to receive the reduced Screw threaded extremity 2Ov of a stud 21. The body of the 'stud 21 'is' provided With a coarse thread adapted to Hinged ,to the upper edge of one of the sides ofthe casing 9 is a lid 23 which may be of considerable depth yas shown. The lid 23 is preferably hinged along the.v same i side ofthe'casmgl as is the cover 17 and the lid 23 isprovided'vvithv kaA cleat 24 which will engage the cover 17 and retainthe same in closed position when the lid is closed, irrespective of the position of the casing. The cleat 24 vis so' proportioned and posi'- 70 lboard 'as is common and the turn-table is Y- remox'f'ably carried thereon -v1n such va manner the lid 23 on being closed will automatically lower the cover 17, `and positively close the compartment containing the 'tone-arm and prevent the cover 17 from opening until the lid 23 is raised.

Attached tothe inner side of the lid 23, is a plate25, having` a screw threaded oritice. By screwing the stud 2l into this orilice, records not in use when the machine is being played may be supported on said stud and secured in place by the nut 22, thus leaving the turntable free for the record in use.

Instead of employing a deep lid 23 the same may be iiat whereby the depthof the casing or cabinet, as a whole, will be greatly reduced.

The operation is as follows:

Zhen the device is not in use the tone-arm is removed from its operative position in communication with the horn and placed within the recess 13.`

The reduced extremity of the stud 21 is screwed into the recess in the spindle 2. The records 27 'intended for future use are now positioned on the turn-table. The lowermost records will encircle the end of the spindle and the remainder will engage the stud. The nutv22 may now be applied to the stud, and the records will be securely locked in position, when the lid 24C and side 11 are closed and loclred in closed position,

When in use the Ystud and discs are removed froni the turntable, and the stud` is screwed into the fitting in the cover, which is in the position shownl in Fig. 4l, and the records are placed thereon as before, and may be used as desired.

In accordance with the provisions of the patent statute, I have described the principle of my invention together with the apparatus which I nowl consider to represent the best embodiment thereof, but I desire it understood that my invention is not conherein shown and described is only one yof v many that can be employed to attain these objects and accomplish these results.

I-Iaving now described my invention, what I claim and desire to secure by Letters Patent, is A portable phonograph comprising a rec-l tangular lidded receptacle, a horizontal par- 'tition dividing said receptacle into a deep lower compartment and a shallow upper compartment, a vertical, diagonally disposed, contrary flecturedpartition dividing said lower'compartment and delimiting withL said horizontal partition, a side wall and the base of the receptacle, a flared ampliiier the mouth of which is substantially co-eXtensive with the width of said receptacle, the space `behind said vertical partition containing a motor and a locker for detachable parts of the phonograph mechanism, -said motor having one `corner adjacent the center of said vertical partition and from which corner projects the turntable spindle, whereby said spindle is located in the center of the hori- Zontal partition, a tone yarm collar located at the corner of vsaid horizontal partition and opening into said amplifier.
